Remix Application Template

⚠️ Be warned: This template is currently work in progress and has not been tested in production yet.

Bootstrap a Remix and TypeScript application with Continuous Delivery

Prerequisites

Node.js

We aim to use the current active LTS version of nodejs, which is V20 at the time of writing. There is a .node-version file to simplify setup using nodenv.

Testing

For E2E and a11y testing with Playwright you will need to install the supported browsers:

npx playwright install

Git Hooks

For the provided Git hooks you will need to install lefthook (git hook manager) and talisman (secrets scanner):

brew install lefthook talisman
./run.sh init

The following hooks are specified in the lefthook.yml:

• commitlint - write conventional commit messages
• lint - avoid committing code violating linting rules
• format - avoid committing wrongly formatted code

Before pushing, the following checks are additionally ran:

• licenses-audit - uses license-checker to verify depency licenses
• secrets-audit - avoid accidental pushes of secrets and sensitive information

security.txt

This template contains a security.txt, where you probably want to update the expiration date. The following entries may also be added:

Policy: https://raw.githubusercontent.com/digitalservicebund/<<REPO_NAME>>/main/SECURITY.md
Canonical: https://<<PROJECT_URL>>/.well-known/security.txt

Development

From your terminal:

npm run dev

This starts your app in development mode, rebuilding assets on file changes.

Testing

The application has

• unit tests (using Jest)
• end-to-end tests (using Playwright)

Test commands

• Run unit tests: npm test
• Run unit tests with watcher: npm test -- --watch
• Run E2E tests: npm run test:e2e

Code quality checks (linting & formatting)

The project uses ESLint for linting and Prettier. for formatting.

Commands

• Check formatting: npm run format:check
• Autofix formatting issues: npm run format:fix
• Check lint: npm run lint:check
• Autofix lint issues: npm run lint:fix
• Check style (formatting & linting): npm run style:check
• Autofix style issues (formatting & linting): npm run style:fix

Deployment

Build and run the app in production mode:

npm run build
npm start

Docker

The project includes a Dockerfile to create a Docker Image for the project.

You can build the Docker Image using

docker build -t remix-application-example .

and then start it using

docker run -d -p 3000:3000 --name remix-application-example remix-application-example

If you want to include any files during the build that are not in the app or public directories you need to add them to the .dockerignore file.

DIY

If you're familiar with deploying node applications, the built-in Remix app server is production-ready.

Make sure to deploy the output of npm run build

• build/
• public/build/

Architecture Decision Records

The docs/adr directory contains architecture decisions. For adding new records the adr-tools command-line tool is useful but not strictly necessary:

brew install adr-tools
